Just do not use this company...they will shortchange you!!

I sent my iphone 4 off to this company 3rd September. They promised me £132 for it.
I sent it off in the envelope, fully protected from any breakages..i also sent it special delivery sign for at a cost of &6.95 to ensure they received it safely and promptly.
I finally heard from them via email about a week later...I knew they'd got the phone the next day after I sent it...so it took them some time to test it and get back to me.
They offered me a measly £40 for it...saying the back was cracked....now when I sent that phone off it was in pristine condition...and I packed it correctly...and I sent it by special delivery..
If I declined their offer I was going to have to pay out for more postage..for it to be sent back to me....
I only have their word it was damaged...but after reading comments online after sending this phone to them...why oh why did I not do more research...I discovered that they do this a lot...
I accepted their offer of £40 as I just wanted the matter dealt with and finished. I didn't want the hassle, as I have enough going on...but the fact of the matter is this...they then have the cheek to make you wait a very long time to get the money..
On 13th September I was told 7-10 days for the £ to hit my bank account, now I query again today as it has been 10 days exactly and still no £. They now change it to 7-14 WORKING days...that now means could be 4th October I get the £.
To clarify...they got my phone on the 4th September...that means it will of taken them a whole month to pay me for it...and a lot less than I was actually promised...
Note to oneself...do not go onto a price comparison website for phone recycling again, as I went for the biggest offer...and now look where I am...they have my phone, I still do not have my money...I should of just sold it on ebay and made loads more money for a phone that was in pristine condition...am very annoyed at this situation.
Jolly well fed up with having to chase it up too, as far as I am concerned they have cheated me out of money...and then they now have the cheek to make me wait a very long time for the measly amount of money they are going to pay me.
Not happy at all!!!!!!!
